Abstract: A system includes an aftertreatment system and a controller coupled to the aftertreatment system. The controller is configured to generate a spatially resolved model of a catalyst of the aftertreatment system. The controller is further configured to adjust the spatially resolved model based on one or more sensed values from at least one sensor upstream of the one or more portions and at least one sensor downstream of the one or more portions.
